RAILWAY-TIE.

Specification of Letters Patent.

Application filed January 15, 1906. Serial No. 296,194.

dent to the passing of trains over the track.`

With these and other objects in view the present invention consists in the combination and arrangement of parts, las will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a top plan view of a railway-tie embodying the features of the present invention. Fig. 2 is a side elevation thereof with thel adjacent guard-plate removed. Figs. 3 and 4 are views similar to Fig. 2, showing modified arrangements. Fig. 5 is a cross-sectional view on the line 5 5 of Fig. 2. Fig. 6 is a detail perspective view ofone end of one of the tie-sections. Fig. 7 is a fragmentary perspective view of one of the guard-plates.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

The present tie includes upper and lower duplicate sections 1 and 2, each of which is in the nature of a flat metallic bar having the necessary dimensions for a cross -tie. At each end of each tie-section there is a longitudinal seat which is open at its inner end and formed by longitudinal flanges 3 and a cross-liange 4 at the extremity of the section. The flanges of the upper section depend therefrom, and the flanges of the lower section rise therefrom.

interposed between the tie-sections is a plurality of zigzag spring-plates, preferably arranged in groups of three, as shown at 5 In this arrangement of springs the downwardly bowed or inclined portions of the lower group of springs bear upon the bottom tie-section 2, while the upwardly bowed or bulged portions of the upper set of springs` bear against the under side of the upper tie-section, while the downwardly-bowed portions of the upper set engage the upwardly-bowed portions of the lower set, whereby each set of springs bears at intermediate intervals against the adjacent tie-section and also against the other set of springs. The terminals 7 and 8 of the respective sets of springs are disposed in substantial parallelism with the tie-secti ons, the lowermost member of the lower set being received within the adjacent seat formed by the flanges 3 of the lower tie-section, and theV uppermost spring of the upper set having its terminal received within the adjacent seat upon the under side of the upper tie-secti on, thereby to give the springs terminal bearings against the tie-sections. Suitable fastenings 9, such as bolts, pierce the tie-sections and the springs, it being preferred to have one of the bolts pass through the middle of the tie and the other bolts disposed so as to passA through the springs where they come into'engagement with one another. To accommodate for the necessary endwise play of the springs when under compression, the openings for the reception of the fastenings 9 are u slots, as shown at 10 in Fig. 2. By preference other the tie-sections beyond the ends of the sets of. springs and pass through the terminal flanges 4.

Guard-plates 12 are applied to the opposite longitudinal sides of the composite tie, so as to close the space between the tie-sections, and thereby prevent ballast from working in between the sets of springs and the tie-sec- .85 fastenings 11 connect the ends of tions, which would interfere with the yieldable characteristics of the tie. Each of these guard plates is provided with terminal flanges 13 to embrace the ends of the tie-sections to which they are secured by suitable fasteningslii. The guard-plates are secured to. the tie-sections by suitable fastenings a, and the plates are provided with vertical slots b (shown in Fig. 5) to permit the desired vertical movements of the upper tie-section.

For the accommodation of the track-rails 15 the upper face of the upper tie-sections is provided with spaced transverse open-ended seats 16 to receive the bases of the rails, suitable retaining-plates 17 being secured to the upper face of the tie-section 1 and overlap- ICO IIO

vping the bases of the rails, so as to hold the l latter in their seats. Bolts 18 are employed to hold the plates 17 in place.

In a tie constructed as hereinbefore described the upper section thereof is yieldably supported in an elevated position upon the lower tie-section, and when the weight of a train comes upon the tie the upper tie-section yields so as to cushion the passage of the train across the tie, and thereby render railway travel more comfortable than with the ordinary non-yieldable ties. By reason of the fact that I employ relatively long broad fiat spring-plates and give them va series'of bearings against one another and against the tie-sections the strength and durability of the tie are materially increased and there is little or no liability `of the springs becoming broken. As a plurality of springs are employed, should one of them become broken the yieldable qualities of the tie will not be materially imp aired.

Instead of employing two sets of springs, as in Fig. 2, I may employ onlyone set of springs, as shown in Figs. 3 and 4, the set of springs 19 in Fig. 4 being substantially the same as the set of springs 6 in Fig. 2, whereby this set of springs has alternate bearings against the tie-sections 1 and 2, so as to yieldably support the upper tie-section in a thoroughly-satisfactory manner.

The set of springs 2() in Fig. 3 bears at its middle against the lower tie-section, from which it inclines upwardly in opposite directions into engagement with the upper tiesectibn, the terminals 7 being disposed in substantial parallelism with the tie-section,` so as to have a broad at bearing thereagainst, the upper and lower spring members of course being received within the seats of the tie-sections ,so as to hold the same against lateral displacement.

Having thus described the invention,what is claimed is- 1. A railway-tie comprising tie-sections, and an interposed zigzag spring-plate.

2. A railway-tie comprising tie-sections, and interposed longitudinally-disposed zigzag spring-plates.

3. A railway-tie comprising tie-sections, and an interposed longitudinally disposed zigzag spring having certain of its zigzag portions bearing against the tie-sections.

4. A railway-tie comprising tie-sections,

and an interposed longitudinally-disposed zigzag spring with certain of its zigzag portions bearing against the tie-sections and its ends disposed in substantial parallelism with the tie-sections.

5. A railway-tie comprising spaced tiesections having terminal seats upon their inner faces, the seats being open at their inner ends, and a zigzag spring disposed longitudinally between the sections and bearing thereagainst with their ends received within' the respective seats.

6. A railway-tie comprising spaced tiesections having terminal seats upon their in.- ner faces, each seat being formed by spaced longitudinal flanges and an outer transverse flange, and a zigzag spring interposed between the tie-sections with its zigzag portions bearing thereagainst and its ends disposed in substantial parallelism with the tiesections and received in the respective seats.

7. A railway-tie comprising tie-sections, a spring interposed between the sections, and guard-plates closing the space between the tie-sections, each plate being rigidly carried by the lower tie-section and having a slotted connection with the upper section.

8. A railway-tie comprising tie-sections, a spring interposed therebetween, and guardplates closing the space between the tie-sections, said guard-plates being carried by the lower section and loose upon the upper section to tion. v

9. A railway-tie comprising upper and lower sections, a spring interposed between the sections, guard-plates applied to opposite sides of the tie and closing the space between the tie-sections, and fastenings connecting the plates with the sections, the plates being slotted to slidably receive some of the fastenings.

10. A railway-tie comprising spaced up-, per and lower-Sections, `and a pair of superposed zigzag spring-plates interposed between the sec-tions and bearing against one another and the respective tie-sections.

In testimony that I claim the foregoing as my own I have hereto affixed my signature ,in thepresence of two witnesses.
